My boyfriend might be cheating

He has a galaxy s7 edge and I went to his google chrome and his autocorrect words were free hook up, live cams of nudes, and he told me he has a bunch of people who share is google account but that don't seem to add up why would it be on his keyboard that he typed that **** so please help?

Sorry there isn't much we can help on. We help with Android things -- not so much relationship advice. The only tech advice I can give is phones don't just type things on their own.. So take that as you will.
